Deceased Account

I have a complain about this debt collection .I am Alina my mom has a account with Jet and she was a good payee.2021/06/01 she passed .We send all the required documents to jet and she has a insurance that pay for 12 months on that card and they pay all the money .Lat year they call me enquire about my Mom so I was surprised because we send death certificate and ID .been receiving the email from them its irritating me .I call them from their store ,I spoke with Faiza Patel and send again the document every time they send me statement and outstanding what I know each and every account has the card credit protection plan .Those who are responsible they need to sort it out .
